SUBSEA WORKS

Description

STM has supported the Offshore Operator in umbilical tie in operations and umbilical lay.
Checking step by step the umbilical stresses from wave actions.
STM predict the maximum line tension and bending moment for the return period of sea of operation, this allows the Operator assessment of goodness of fit, appropiateness of selected method and to define sea state limit for the operations.
Vessel’s RAO provided by the ship Owners enabled STM to assess the vessel motion and to calculate the accelerations in way of COG to the 400 ton Reel with the coiled umbilical.
STM verified by FEM/FEA the vessel deck strenght and designed the fastening of reel and equipment .
